10 Claims. (Cl. 268-404) This invention relates to a window. operatorcombination in which the sash may be moved to its various positions bymeans of a mechanism wherein the forces employed to effectuate themovements necessary to adjust the sash are exerted upon the. sash'through the medium of ilexible but substantially longitudinallynon-compressible rod or equivalent member such as a wire, and throughwhich the forces are transmitted in directions, longitudinally of saidmember.

One advantage of this invention lies in the fact that the necessity forsuch elements as cranks, levers, gearing and similar force transmittingelements between the sash and the actuator is reduced to the minimumwith the result that the forces applied to open and close the windowsash are converted intorthe maximum available power.

Another advantage of this invention lies in the fact that the device inwhich it is embodied is relatively simple, sturdy, easily installed andmaintained and will consume a minimum of space. s

In addition tothese advantages a device embodying this 'invention willnot only operate to open and' close the window sash when it is actuated,but Vwill also maintain the sash in its open arid closed positions andadditionally may be used to forcibly set the sash up against the weatherstripping with a weather stripping compressive force.

. Other advantages will appear from the description of the embodiment ofthe invention illustrated in the drawings and described in thespecification.

While the invention is Lapplicable to windows having sashes of differenttypes, Iv shall describe it in connection with what is currently knownas an awning window and itis thus illustrated in the drawings.

In these drawings: f i Y Figure l is a face View of an awning typewindowwith one light;

Figure 3 is a horizontal sectional view on line 3 3 of Figure 1 lookingin the direction of the arrows;

Figure 4 is a vertical sectional View on the linev 4 4 of Figure 1looking in the direction of the larrows but with the sash partly open;,Y

Figure 5 is an enlarged viewA of one of the operator members and aportion of the actuator taken on line 5 5 of Figure 4; g

Figure 6 is a vertical sectional view on line 6 6 of Figure 5 looking inthe directon'of the arrows;

Figure 7 is a horizontal sectional View on the line 7 7 of Figure 5looking in the direction of the arrows;

Figure 8 is a horizontal sectional View on line 8 8 of Figure 5 lookingin the direction of the arrows;

Figure 9 is a sectional View on line 9 9 of Figure 8 looking in thedirection of the arrows; and

Figure 10 is a sectional view on line 10 10 of Figure 2s looking in thedirection of the arrows.

The window to which the operator of this invention is applied and whichis depicted in the drawings for illustrative purposes; comprises a framehaving a header 1,

HCC

a sill 2 and jambs 3 as illustrated in Figure l. Each of the jambs 3 isprovided with a longitudinal, vertically extending chamber 4 as shown inFigure 3. The header 1 is provided with a longitudinal, horizontallyextending chamber 5 and the sill is provided with a longitudinal,horizontally extending chamber 6 as illustrated in Figure 4 of thedrawing.

The header maybe provided with compressible weather v stripping such as7, the sill with a similar weather stripping such as 8 and the jambswith a weather stripping such as 9, all of which are so arranged as tobe contacted by and compressed by the sash when the latter is moved intoits closed position.

This sash is mounted as follows: In each of the chambers 4 in the jambsa plurality of guide rollers 9' are f mounted on the jamb. An elongatedslide 10 is mounted on these guide rollers for vertical movements inupward and downward directions.

Adjacent the lupper end of each slide the sash 11 is pivoted at 12 toswing about these pivots into opened and closed positions. l

To each side of the sash a stay-bar 13 is pivoted at 14, the stay-barbeing pivoted also at 15 to the jamb.

Thus when the slides are moved downwardly the sash will be moved towardits open position about the pivots 12 and when the slides are movedupwardly the sash will be moved toward its closed position. This isbecause the pivots 12 move vertically with the slides while the pivots15 have no such movement.

- In order that the sash may be moved to its open position and to itsclosed position, maintained in such positions and sealed against theweather stripping around its entire perimeter, I have provided thefollowing mechamsm:

A relatively stijf, resilient and substantially non-compressiblelongitudinally operating member such as a wire 16 or its equivalent, isattached to each of theV slides 10 at a convenient point such for`instance as at its upper end `as shown in Figure 4 by such means as willhereinafter be described. VThese operating members 16 are located withinthe chambers 4 of the jambs and extend downwardly towardk the sillinsuibstantially rectilinear directions. They also follow rectilineardirections within the chambers 6 of the sill toward the center thereof.Between the two rectilinear portions of each operator lthe operatorfollows a curvilinear path. The two rectilinear portions are indicatedbythe reference numerals v17 and 18 and the curvalinear portion by thereference numeral 19.

The ends of these operating members 16 terminate adjacent each otherpreferably near the center of the sill and in overlapped relation.

When the rectilinear portions 18 are moved longitudinally outwardly, i.e. toward the respective jambs, the vertical rectilinear portions 17will be moved upwardly, the force being applied through the curvilinearportions 19, with the result that the slides 10 will be moved upthe sametime to providea protective covering, I have l provided the following: Y

Each of the operator members 16 is housed within a relatively rigidtubular member 20, -a portion 21 ofwhich is located within and extendslongitudinally of the sill chamber 6 and another portion 22 of which islocated within and extends longitudinally of the chamber 4inV a jamb.

These two portions of the tube are substantially rectilinear andunlitedby an integral curvilinear portion Z3. These three portions of the tube`determine the directions of the operating member 16,

The tube is made rigid with the window frame by suitable devices such asindicated at 23 in Figures 3, 4 and 5. It may be made integral with thewindow frame.

The -operating member 16 is encased in a sheath and force transmittingmember 24 which is preferably in the form of a helically coiled springwith insubstantial compressibility. This sheath, while snugly 'fittingwithin the tubular member 20, is capable of free sliding movementtherewithin. The inside diameter of this sheath is such that theoperating member 16 ts snugly therein and is thus prevented from havingundesirable lateral flexing during operation.

A tubular extension 25 is `mounted on and envelopes therupper end ofeach of the tubular members and is freely movable `on the tubularmember. This exten# sion is secured to a bracket 26 which is providedwith a bearing member 27 and is secured at `28 to the adjacent slide 10.The bearing member 27 1islprovided with a bore 29 through which a rod 30freely extends; To the lower end of this rod Athe operating member 16 isixedly attached. The upper end of the rod is threaded as at 31 and isprovided Vwith a locking nut 32; An adjusting nut 33 is 4in screwthreaded engagement `with this rod and is provided `with a dependingsleeve 34 which is iixedly secured `to the extension 25 of the tubularmember.

Inasmuch as the tubular member is tixedly secured to the frame of thewindow `as'at 23', the adjustment of the nut 33 will adjust theextension 25 of the tubular member on the main body portion of thelatter in which i position yit `may be locked by the lock nut 32.

Thus when the operator is Ioriginally installed the relative positionsofthe operator elements in respect to each other `and in respect to thesash on both sides of the window may be adjusted so that in subsequentoperation equal forces willbe applied to both sides of the sash,

ber is such as to permit this block to move sufficiently for the openingand closing of the window sashes.

The other of the two operating members 16 is provided with a similarblock similarly mounted. The sheath 24 freely abuts the 'block 46 at itslower end at 24' and also freely abuts the lower end of the rod at itsupper end at 24 so that when the block 46 is moved longitudinally withinthe tubular member 20 the oper- -ating member 16 and the sheath 24 willmove as a unit with the block and with the rod 30. Rigidly connected toeach block 46 is a coaxial rod 47 which is provided with a plurality ofspaced abutments 48 which are rigid with the rod. The inside diametersof the portions 21 of the tubular members 20 -of the extensions 20' andof the openings 40,411,42 and 43 are substantially the same and thediameters of the labutment members 48 are only sufficiently less thanthe inside diameter of the tubular members and they openings to permitfree longitudinal movements of the abutment members within the same. Aswill be noted from Figure 9 of the drawing, the

i two operating members 16 in effect overlap, but as disclosed in Figure5 of the` drawing, terminate short of the ends of the extensions 20 ofthe tubular members 20 so that the operating vmembers may have freedomof movement in the tubular members longitudinally of themselves. t

In order that the operating members may be moved longitudinally to openand close the sash simultaneously,

l I have provided the following mechanism: An actuator thus insuringtrue -opening and closing ofthe sash ony the pivots vwithout anydistortional tendency.

In order that the operators 16 may be actuated to move in bothdirections longitudinally of their long` axes, I 'have provided thefollowing mechanism: a housing '35 -is `provided `and may be mounted onthe sill in 4such a position as indicated in Figure l of the drawing.This housing is constituted preferably by a lower housing member 36 anda superimposedupper housing member 37 which are secured rigidlytogether, the lower member being provided with a recess 38 and theruppermember with a recess 39 which together forma chamber in thehousing. The lower housing member 3,6 is provided with aligned openings`40 and 41 which extend through the wall of the lower housing -member`36. `A secondpair of aligned openings 42` and 43 which aresubstantially v parallel to the first mentioned openings extend throughthe wall of theV housing member 36 as illustrated in `Figure 9 of thedrawing. An end of ,one of the tubular members 20 is secured to thehousing as at 44 in ,alignment with the opening 40 while an end lof the`other tubular member` 20 which Ais aligned with the opening V45 issecured 'to thehousing as at 45. v

Extending from thefopening 41 is an aligned extension 20 of the tubularmember 20 which is aligned with the opening 41and extending from theopening 42 is a similar `extension 20'.

One of .the operating members 16 is rigidly secured to a block 46which-is mounted within the tubular member 20 located within the sill ofthe window. The diameter of this block 46 is such that it may have freelongitudinal movements within 'the tubular member and the length ofitherectilinear portion 21 of the tubular memis locatedwithin thehousing 35. A disc 49 somewhat in the `form of asprocket is locatedwithin the recess 38 of the chamber of the housing 35.` This disc orsprocket is provided with projections 50 and recesses 51, theprojections being substantially radial and being bifurcated as shown inFigure 8 of the drawing for the reception of the rod members 47. `Theprojections 50 are adapted to extend into the spaces between theabutments 48 and to engage the same so that upon rotation of thesprocket 49 the portions of the operating members 16 located within thechamber yof the sill will be moved in opposite directions thus `movingthe vertical portions of the 4operating members either upwardly ordownwardly depending upon the direction of rotation `of :the sprocket49. During the engagement of the projections 50 with the abutments 48the latter will successively seat Within the recesses 51 of the sprocketas disclosed in Figure 9 of the drawing `as the sprocket is rotated.

Formed rigid with this sprocket member 49 is a gear 52 which is spacedyfrom the sprocket member by a hub 53 and is located in the recess 39 ofthe chamber ofthe housing 35, the gear being coaxial .with the sprocket.A cooperatingworm 54 which is engaged with the gear 52 is suitablymounted in bearings within the `housing 35 and is provided with anoperating handle 5S `which is accessibleat the inside of the Window. Itmay be here pointed out that the gear 45 is in the form of a helicalLgear which insures through the engagementof the worm 54, the maintenanceyof the ysprocket 49 in its various positions of rest.

When the operating handle 55 vis actuated ,the worm 54 will rotate thehelical gear 52 and through the hub 53 the sprocket member 49 will berotated in a direction dependent upon the `direction of rotation of `theworm 54. Because of the engagement of the sprocket member 49 with theabutments 48, the rotation of the sprocket member in one direction willcause the rods 47 t0 move outwardly toward the jambs. This movement ofthe rods will move the blocks 46 within the tubular members 20 andbecause of the presence of the sheath 24 and the operating member 16 andthe abutment of the sheath against the block 46 and the rod 36 on eachside of the Window the bracket 26 will be moved upwardly,` thesecurement of tbe'brackct 26 on each side of the window to the adjacentslide at 28 eiectuates the upward movement of the slides andconsequently closes the sash.

When the operating handle 55 is actuated in the opposite direction themovement of the operating members 16 will be in the opposite directionand as a consequence the slides 10 will be drawn downwardly thus causingthe opening of the sash.

It is here pointed out that when the actuator is operated to move thevertical portions of the operating members 16 upwardly the force will betransmitted to the slides 10 not only by these operating members 16 butalso by the sheaths 24, the two elements on each side of the window thusforming a compound operating member during such vertical movement.

Because of the sturdiness of the construction, pressure may be appliedto the operating handle 5S near the end of the closing movement of thesash so that the weather stripping will be compressed to seal the sash.The sash will be held in this closed position by the locking action ofthe helical gear and the worm with which the handle 55 is provided.

Each operating member 16 may be made of a relatively small diameter wireof steel but the wire may be made of various other materials havinglateral flexibility and substantially no extensibility orcompressibility longitudinally of itself. Moreover the sheath 24 may bemade of metal or of other desirable materials which will not only guidethe members 16 and assist in the movements of the slides but will alsodampen any noises that may result from the movements of the operatingmembers.

While I have illustrated and described the operator as applied to whatis currently known as an awning window, it is to be understood that withcertain modications it may be adapted to operate windows of other types,such as Casement windows and double hung windows, by way of example.
